Using pipe cleaners, straws, and beads, learners explore the building blocks of life by creating their own model of DNA.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

Working in small teams, learners try to build a satellite that can float for at least five seconds in the marked area of a vertical wind tube.

In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.

In this activity (on page 2 of PDF), learners make their own totem poles out of recycled materials.

Play with your food while learning about engineering! Build a spaghetti bridge, then test its strength by piling on the marshmallows, raw spaghetti, raw linguine and coins.

Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

In this activity, learners imitate the way vocal cords work by building a model from a plastic cup, rubber band, and a straw.

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

Investigate how force and thrust work to propel rockets into outer space. Build a rocket: a blown-up balloon taped to a drinking straw threaded through some string.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.

In this activity, learners will use their chosen material to build the tallest tower possible in under three minutes. This activity uses problem solving and fine motor skills to challenge learners.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.
